Welcome to the Electric Power Research Institute's Energy Storage Vendor Database (ESVD), a snapshot of the present landscape of the energy storage industry. The ESVD is meant to provide a surface-level understanding of the different technology developers in the space, with their technology types and company status being of primary interest. This database can be quickly built upon to add future energy storage technologies and update the status of those already on the list.
We believe this resource can bring value to EPRI researchers, members, and the general public by providing a complete list of energy storage developers. As this list is meant to represent the extent of EPRI's knowledge of the players within the energy storage space, it is in our interest to include every entity working on energy storage technologies in this database. If there is an energy storage technology that is not on this list, you can contact Kelyn Wood at kwood@epri.com to add it.
